furrow: [OE] Furrow is an ancient agricultural term, going back to the prehistoric Indo- European base *prk-, which also produced Welsh rhych ‘furrow’, Armenian herk ‘newly ploughed land’, Latin porca ‘ridge between furrows’, and possibly also Sanskrit parçãna- ‘chasm’ and Latin porcus ‘grave’. Its Germanic descendant was *furkh-, which produced German furche, Dutch voor, Swedish fåra, and English furrow. => furlong
